Abstract
In a method for molding a laminated assembly comprising a resin core member, and a surface skin member either partly or entirely placed over the surface of the resin core member, the dimensional precision of a part of the surface skin member involving a high rate of extension is improved, and the cushioning property and the surface quality of this part are avoided from being impaired. An approximately molded portion is defined in a part of the surface skin member involving a relatively high rate of extension during the vacuum molding process using a vacuum molding die assembly, and the thus molded surface skin member is mounted on the upper die for mold press forming with a gap defined between the approximately molded portion or an unmolded portion and the associated die surface. During the mold press forming process, the pressure of the semi-molten resin material molds the surface skin member into its final shape so that the molding precision of the part of the surface skin member involving a high rate of extension can be improved. In particular, when the surface skin member is lined with a foamed lining layer, damage to the foamed lining layer of the surface skin member during the process of mold press forming is minimized.
